"I've won several tournaments with the BlackWidow as of now, thanks to the lightning fast clicking speed it provides. The BlackWidow never let me down in all those tournaments and it's still impressing me. Perfect choice for fast paced games like Counter-Strike."

look, I own blackwidow.
yes you often accidentally press the wrong key because it's so light.
No, it's better than black for gaming because you press the keys lighter. you don't get tired as fast as terrible rubber dome keyboards.

Not so much for basic movement, however difference in keyboard really shows when playing kz. For example, with my keyboard I can't physically make more than 6 strafes per a single longjump, and I can fully control only 5 strafes per jump, just because I can't press buttons fast enough.

Same should go for counterstrafing, except that difference isn't that noticeable.
